RESUMO

Objective:To investigate the current basic situation of the staff of ultrasound departments in Shanghai′s medical institutions, for providing references in making management policy of these professionals.Methods:Questionnaire surveys on human resource and service ability were made to all the ultrasound departments of medical institutions in Shanghai in December 2013 and November 2018 respectively. Data of the two surveys were compared and analyzed, and were descriptively analyzed by mean and percentage.Results:The number of ultrasound professionals per 10 000 people in Shanghai was 1.04 in 2018. Tertiary hospitals had advantages in the number of the professionals, and the proportion of professional qualification, age, education background and professional title of the professionals. Compared to those data in 2013, the number of ultrasound professionals had increased 31.8% in 2018. The proportion of medical practitioners with medical imaging specialty was 95.6%(2 063/2 158), and had increased by 4.7 percent. The medical services workload of ultrasound was 19.82 million person-time, and had increased 45.8%.Conclusions:Development of ultrasound departments was rapid, but the development of professionals was unbalanced with the development of medical services. It is suggested to strengthen training of ultrasound professionals and improve the system of hierarchical medical system.

RESUMO

ObjectiveTo investigate the value of combined four-chamber view,left and right ventricular outflow tract view and three-vessel view of two-dimensional echocardiography (2DE) in prenatal screening for fetal congenital heart disease (CHD). MethodsFour combined views of 2DE were used to detect fetal hearts in 2419 fetuses at 21~ 25 gestational weeks.The echocardiograms were performed on all 2382 live-birth infants.Chi-square test was applied for statistical analysis.Sensitivity,specificity,positive predict value and negative predict value were calculated. Results The prevalence of fetal CHD was 11.62% (281/2419).Among the 281 CHD fetuses,87.18% were simple CHD (n=245) and 12.82% were complex CHD (n=36).No difference was found in the positive rate of fetal CHD between the high-risk group and non-high-risk group [13.60%(34/250) vs 11.39%(247/2169),x2=1.069,P<0.05].Thirty-six cases of CHD could be detected by the four combined views in prenatal screening with the sensitivity,specificity,positive and negative predictive value of 12.8%,99.8%,90.0% and 89.7%,respectively.However,the diagnostic sensitivity of four combined views for simple CHD was 2.9%(7/245) and 80.6%(29/36) for complex CHD.The prevalence of neonatal CHD was 10.58% (252/2382),including 241 with simple CHD and 11 complex ones. ConclusionsFour combined views of 2DE for prenatal screening is less sensitive in detecting simple CHD than complex CHD.Most of the complex CHD could be diagnosed by four combined views of 2DE before birth,but the misdiagnosis rate is high in simple CHD.The echocardiograms performed on newborns might make up for the lack.

RESUMO

Objective To evaluate the accuracy of prenatal diagnosis of fetal conotruncal anomalies with echocardiography. Methods Fetal echocardiography were conducted for all women in their antenatal visits from Jan 2003 to Dec 2004. The echocardiographic diagnosis was compared with cardiac pathology results. Results Among 2063 women who had fetal echocardiographiy performed, conotruncal anomaly was detected in 28 fetuses with the average gestation of 26. 6 (16-40) weeks when the diagnosis was made, including tetralogy of Fallot (n=5), double outlet right ventricle (n = 6) , transposition of the great arteries (n = 5) , truncus arteriosus (n = 9) and ventricular septal defect with suspected overriding aorta (n=1). Four of the 28 fetuses were lost during follow up and the accurate rate of prenatal assessment of the great artery relationship was 75. 0% (18/24). Two fetuses with prenatal diagnosis of truncus arteriosus were reported as having pulmonary atresia with ventricular septal defect at autopsy. An overriding aorta was suspected in the other case, but postnatal echocardiography was diagnosed as perimembranous subaortic defect. Two fetuses with prenatally suspected double outlet right ventricle were diagnosed as having transposition of the great arteries at autopsy. Only one false-negative diagnosis was made in this series (4. 2%). Conclusions Conotruncal anomalies can be correctly diagnosed by fetal echocardiography. A combination of different views is necessary to define the exact spatial relationship of the great arteries. Specific diagnosis remains a challenge in some cases.
